Abstract (Summary)
Hepatitis B is, according to the Ministry of Health of Brazil (1994), the disease withhighest contamination risk and prevalence causing among the known occupationaldiseases in Dentistry, the highest number of death and interruptions of dentist?s clinicactivities. The use of vaccine is essential before the beginning of the professional life.The aim of this paper was to evaluate the soroprevalence of B hepatitis in a individual120 surgeon dentists (CD). The clinic-epidemiologic data and information about thevaccination were obtained through a individual self-applicable questionnaire. Theserological anti-HBs, anti-HBc e AgHBs were tested by the enzyme linkedimmunosorbent assay method. The results show that 5.83% were positive to anti-HBc;however none of samples was positive to AgHBs. The results show that 53,4% of theCD received 3 doses and an extra, 4 (3.33%) were vaccinated with 1 dose, 18 (15%)with 2 doses, 30 (25%) with 3 doses and 4 (3.33%) didn?t answered the question. Theinterval between doses was observed among 72.1% of subjects, against 15.3% that didnot observed it and 12.6%, that didn?t know. Among the samples, 21.7% showed levelsof anti-HBs lower than 10 mIU/ml thus considered ?Negative.? The statistical dataanalysis revealed that the differences observed among the groups were statisticallyrelevant only when related to ethnical group and the interval between doses. The resultsshown that the highest frequency of immunized individuals had had three doses plusbooster; the level of accidents with sharp instruments was high; the seroprevalence ofdentists anti-HBc+ was low. There was no case of detection of AgHBs; the percentageof vaccined dentists in Salvador that is not protected is high Hepatitis B is, according to the Ministry of Health of Brazil (1994), the disease withhighest contamination risk and prevalence causing among the known occupationaldiseases in Dentistry, the highest number of death and interruptions of dentist?s clinicactivities.
